Does anybody know what part number for a QE front diff works in a 13" mav or does it even matter. I've found about three or four different part numbers and each have different prices. Will they all work? Obviously I want to buy the cheaper one which from what i found is the one for a 12" renegade. I bought the one for the renegade and put in my commander and it worked fine so I guess I just need to know will it work in the mav.
